The flat link chain that starts said type can be installed in the vehicle drive unit.When using in stepless conical pulley flexible drive transmission (CVT) as the part of transmission for vehicles, pressure piece has the end face of special shaping, between awl dish and flat link chain, transmits pulling force as frictional force through these end faces.In the most application of in vehicle drive unit other, flat link chain is a toothed chain, and therefore this toothed chain has tooth at least one side, between gear and chain, transmit pulling force through these teeth.This flat link chain that is the toothed chain form for example can be installed in the auxiliary unit that perhaps can be used for the wheelbase of cross-over connection and differential mechanism or for example also can be used as the force transfering device use in the auxiliary drive or be used for Motor Vehicle in the transfer case of full wheel drive Motor Vehicle at this.
Flat link chain is made up of a plurality of link plates at this; These link plates are through pressure piece hinge connection each other; Link plate is arranged in the form that this can be the contact pin group like this: a plurality of link plates be adjacent to each other ground and passed by pressure piece abreast each other; So obtain a flat link chain thus, this flat link chain can bear tensile load ground and transmit big power.
For example by means of US 5,651,746A is known this flat link chain.This known flat link chain has pressure piece, and these pressure pieces are mutual to putting with transmission power on rolling surface.These rolling surfaces based on radius be called as the best at this in the window inside relevant with pitch.To realize the damage in advance that this known flat link chain is not kept thus in the zone of rolling surface during bearing load in advance.If transmit pulling force through this known flat link chain now; Then because the geometrical shape of the rolling surface of pressure piece and can be created in pressure piece and the disadvantageous power distribution in the zone of putting face of leaning on link plate; It is dangerous and cause peak stress, this peak stress to promote that flat link chain lost efficacy in advance thus that this has improved that rocker pressure piece reverses in the hole of link plate.
Summary of the invention
Set out thus, task of the present invention is now, and a kind of flat link chain is provided, in this flat link chain pressure piece with link plate by the zone of putting face in exist more favourable power to distribute, eliminate said problem thus.
Now, in order to solve this task, the present invention proposes a kind of flat link chain; In particular for vehicle drive unit; This flat link chain has a plurality of through the pressure piece link plates that connect of hinge each other, and wherein, pressure piece laterally extends with respect to the longitudinal direction of flat link chain and is arranged in the hole of link plate; On pressure piece and link plate, be configured with separately construct arching by putting face; Pressure piece and link plate along these by putting face each other by putting with transmission power, pressure piece be provided with construct the rolling surface of arching, pressure piece along the mutual roll extrusion of these rolling surfaces with transmission power; Pressure piece is constructed asymmetricly on the pressure piece short transverse in the cross section that the longitudinal direction along flat link chain extends; By put face be arranged between pressure piece and the link plate the surface of contact zone that is in top on the pressure piece short transverse be on the surface of contact zone of bottom, wherein, pressure piece has at least two zones with different curvature in the zone of rolling surface.

BWith in the right side of Fig. 6 accompanying drawing half one, to compare difference less, thus, the resulting component stress in the link plate is also corresponding in view of the above to be reduced and breaks to form dangerous the reduction in the link plate thus.
Fig. 8 of accompanying drawing show qualitatively now pressure piece at flat link chain 2 according to the present invention to 1,13 second contact area 7 in the distribution of compressive load per unit area.
This view makes at this to be understood without a doubt; Because the curvature in the zone of second contact area 7 is less; It is such result that compressive load per unit area distributes: it is constructed evenly owing to curvature is little and is not equivalent to for example go up in short transverse (double-head arrow H) lens of jumping-up, is the sort of situation in known flat link chain.
Fig. 9 of accompanying drawing also illustrates now; The central point 8,9 that is used to form the radius of first contact area 6 or second contact area 7 is positioned at vertical line 17 tops, and said vertical line will separate in vertical with the line segment that is connected between second contact area, 7 tops 19 observing first contact area, 6 tops 18 lay respectively at the outside on the pressure piece short transverse H in the heart.The extending longitudinally of first contact area 6, promptly roughly has the double numerical value of the arc length of rolling surface 5 in the zone of second contact area 7 at this along the arc length of rolling surface 5.
Therefore realize that through flat link chain according to the present invention power significantly uniformly by putting between face rocker pressure piece and link plate distributes, thus, the dangerous corresponding reduction of the stress cracking on the link plate.And the different curvature in the zone of the rolling surface through rocker pressure piece makes the different load conditions of bearing in straight flat link chain reversion section and under the bending situation, obtain considering.
